pci_mb.mcp
main.c
pci.c
pci_api.c
Description
Metrowerks motherboard project
Main program file. Main() sets up the exception vector table, and calls PCI routine which initiates
DMA data transfer.
This file contains all the routines that would initialize the PCI bridge of the motherboard and the
add-in and create all the windows in the motherboard and add-in. It also contains the DMA routines
to perform data movement from the motherboard to the add-in.
This file contains convenient API routines that are used by routines in pci.c file.
8260_vads_init.c This is the Metrowerks PQII initialization routine. Note that the software does not make use of this
file. Instead, the software takes the initialization from the debugger configuration file.
intr_PQII_cw.s
This is the lower-level implementation of the interrupt handlers.
